A 7 pole resonator filter including a dual mode resonator and a triple mode resonator may include a first dual mode resonator including independent adjusting portions adjusting each frequency according to two resonant modes, and having at least one conductive surface, a triple mode resonator including independent adjusting portions adjusting each frequency according to three resonant modes separate from the two resonant modes, and having at least one conductive surface, a first connecting portion electrically connecting the first dual mode and the triple mode resonators, a second dual mode resonator including independent adjusting portions adjusting each frequency according to two resonant modes separate from the two resonant modes and the three resonant modes, and having at least one conductive surface, and a second connecting portion electrically connecting the triple mode resonator and the second dual mode resonator. The three dual mode resonators have similar shapes. |
